We are but a collection of days. Each day that passes can and will never return. Any action that is time bound or specific should not be toyed with as missing the time for that action will mean not being able to carry out that action. Any activity to which you wish to expend your time should be properly thought out and not done on impulse.
The reason is that in no distant future that activity may be a source of joy or regret depending on the output from the activity. Do not spend your time on anything that is of no value in attaining your goal in life. Any wasted time will be a source of regret and grief. Time indeed is life, hence wasting one's time is tantamount to wasting one's life.
Those who invest their time wisely today will reap the fruits in future will those do the contrary will live with the burden of regret for haven wasted time.
It is generally quoted that, "Time waits for no one". Truly speaking, we don't have to waste time in anything that is done.
Since the time happens to be so precious, we should always spend our time wisely. When the time is wasted, we stand to lose quite a lot of opportunity in a world of today.
The idea inspires me.
